I have other issues on RSAT regression suite automation tool (including not running in non-admin mode on Windows 11) but I'm now getting an error that blocks execution on the full RSAT. Seems to be popping up on the Selenium forums, perhaps as a webdriver bug:

System.InvalidOperationException: session not created: probably user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir (SessionNotCreated). Help appreciated as this is blocking use of tool.

Regards

Dan
